Since inception in 1985 VTEL has been a global leader in providing tens of thousands of PC-based videoconferencing systems for use in distance education, training, and administrative meetings. The company was the originator of the H.323 videoconferencing standard and originally manufactured a line of traditional codecs that integrated a PC for content-sharing purposes. With the advent of software-based videoconferencing solutions such as Zoom and Skype for Business the company developed an entirely new architecture in which the CPU itself performs all video and audio compression functions, thus leveraging the inherent performance and affordability advantages of this approach.

VTEL was taken public on the NASDAQ exchange in April of 1992. In early 2002 the VTEL Video Systems Division was taken private and company management subsequently developed the aforementioned product architecture which offers significantly greater performance for end-users at a considerably lower cost.
